[0050] like Figures 1 to 8As shown, a massage device and an air suction and discharge drive device thereof according to a first preferred embodiment of the present invention are shown, wherein the massage device comprises an air suction and discharge drive device 1, a flexible massage housing 40, a fixed housing 50, a controller 60 and a power module 70. It can be understood that the air suction and discharge drive device 1 of the present invention is a drive component for driving the massage device. The massage device may include the controller 60 implemented as a circuit board, the power module 70, the flexible massage housing 40 and other massage components such as a vibration massager. The controller 60 and the power module 70 of the massage device may be electrically connected to a drive component 30 of the air suction and discharge drive device 1 to provide power supply to the drive component 30 and control the operation of the drive component 30. The flexible massage housing 40 may be sleeved outside the fixed housing 50 installed on the air suction and discharge drive device 1, and the flexible massage housing 40 may be implemented as a silicone sleeve or a rubber sleeve to be suitable for contacting with a human body part.

[0051] like Figure 2 and Figure 3 As shown in the figure, the flexible massage housing 40 includes a housing body 41 and a head end housing 42, the head end housing 42 has an opening 43, the head end housing 42 and the housing body 41 are connected to form an inner cavity 44 therein for accommodating the air suction and discharge drive device 1, the fixed housing 50, the controller 60 and the power module 70. The opening 43 is connected to the inner cavity 44, and allows air to enter and exit the opening 43 under the driving action of the air suction and discharge drive device 1.

[0052] The shell body 41 and the head end shell 42 can be formed integrally and both made of flexible materials. Alternatively, the head end shell 42 can be made of flexible materials, while the shell body 41 can be made of flexible or rigid materials. In this embodiment, the shell body 41 and the head end shell 42 are integrally formed of the same flexible material such as silicone or rubber, such as by hot pressing, injection molding, etc. to form an integral structure with the inner cavity 44.

[0053] The fixed housing 50 is used to assemble the air suction and exhaust drive device 1, the controller 60 and the power module 70. The massage housing 40 is sleeved on the outside of the fixed housing 50, so that the fixed housing 50, the air suction and exhaust drive device 1, the controller 60 and the power module 70 are accommodated in the massage housing 40.

[0054] The power module 70 includes a rechargeable battery, such as a lithium battery, a lead-acid battery, a nickel-cadmium battery, a nickel-iron battery, a nickel-metal hydride battery, etc., to provide power supply for the controller 60 and the air suction and exhaust drive device 1. The controller 60 includes a control circuit board 61 and one or more switches 62. The switch 60, for example, can be a button, a knob, etc., which is exposed outside the massage housing 40 for user operation. In the example shown in the figure, the switch 62 is a button. The controller 60 can also control one or more control members 63, such as two control members 63, to respectively control the working power of the air suction and exhaust drive device 1.

[0055] like Figures 4 to 8 As shown, the air suction and discharge drive device 1 includes a cavity 10, a plug body 20 movably arranged in the cavity 10, and a driving component 30 for driving the plug body 20, wherein the plug body 20 is arranged in the cavity 10 to form the space in the cavity 10 into a first chamber 11 and a second chamber 12 respectively located on opposite sides of the plug body 20, and when the driving component 30 drives the plug body 20 to reciprocate in the cavity 10, the size of the first chamber 11 and the second chamber 12 can be adjusted, so that the air pressure in the first chamber 11 can be adjusted, thereby providing the massage device with the required suction force.

[0056] In this embodiment, the top side of the cavity 10 has a groove 13, which is connected to the opening 43 of the massage housing 40. The cavity 10 also has one or more through holes 14, such as two through holes, on the top side, which connect the outside of the cavity 10 with the first chamber 11 of the cavity 10. The first chamber 11 is used to generate negative pressure, so that negative pressure is correspondingly generated between the massage device and the human body part, so as to achieve the effect of massaging the human body part by generating suction.

[0057] In this embodiment, the cavity 10 includes a top wall 101, a peripheral wall 102, an extension wall 103 and an end opening 104, wherein the peripheral wall 102 extends integrally to the top wall 101 to form an internal space with an opening at one end, wherein the extension wall extends integrally to the edge of the top wall 101 to form the groove 13 between the top wall 101 and the extension wall 103, the first chamber 11 is formed between the top wall 101 and the plug body 20, the second chamber 12 is formed between the plug body 20 and the end opening 104, and the through hole 14 is formed in the top wall 101 and passes through the top wall 101 to be connected with the first chamber 11.

[0058] That is to say, when the opening 43 of the massage shell 40 of the massage device is close to the human body part, the first chamber 11 can produce a change in air pressure under the action of the plug body 20. Specifically, because the groove 13 is connected to the opening 43, when the first chamber 11 inhales air, the air in the groove 13 on the top side of the cavity 10 is sucked into the first chamber 11, and the skin tissue or muscle of the human body part adjacent to the opening 43 formed by the head end shell 42 of the massage shell 40 is sucked toward the opening 43. When the first chamber 11 is deflated, the air in the first chamber 11 enters the groove 13 on the top side of the cavity 10, and the skin tissue or muscle of the human body part adjacent to the opening 43 formed by the head end shell 42 of the massage shell 40 will be loosened. In this way, the massage device causes the first chamber 11 to produce an air pressure change through the air suction and discharge drive device 1, so that the air pressure changes at the corresponding positions of the opening 43 and the groove 13, thereby realizing a massage with suction on the human body part.

[0059] In this embodiment, the plug body 20 includes a plug body 21, which separates the first chamber 11 and the second chamber 12 and does not communicate with each other, so as to form an environment with adjustable air pressure in the first chamber 11 to generate suction. The cavity 10 can be columnar, so as to form a columnar space inside. Accordingly, the plug body 21 of the plug body 20 can implement a columnar sealing gasket.

[0060] The edge of the plug body 21 may also be formed with an annular positioning groove 22, which is used to accommodate a flexible sealing member 26 such as a flexible rubber ring or a flexible film, which can serve as a waterproof sealing ring, thereby enhancing the airtightness while further preventing water entering the first chamber 11 from entering the second chamber 12 and causing a short circuit of the electronic components.

[0061] The driving assembly 30 includes a driving motor 31, a transmission unit 32 and a driving rod 33, wherein the driving rod 33 is connected to the plug body 21 and is suitable for partially entering the second chamber 12. When the driving motor 31 is working, it drives the driving rod 33 to move back and forth periodically through the transmission unit 32, thereby further driving the plug body 20 to move back and forth periodically in the cavity 10, thereby adjusting the size of the first chamber 11 so that the suction and exhaust drive device 1 generates the suction force required by the massage device.

[0062] The drive rod 33 includes a mounting end 332 at one end adjacent to the plug body 20, and includes a connecting end 333 at the end adjacent to the drive motor 31 away from the plug body 20. The drive rod 33 forms a rod body 334 between the mounting end 332 and the connecting end 333. The mounting end 332 and the connecting end 333 are enlarged ends relative to the rod body 334. The mounting end 332 is embedded in the bottom of the plug body 20 to be firmly mounted on the plug body 20, and the connecting end 333 forms a connecting hole 331.

[0063] More specifically, in this embodiment, the driving motor 31 is a motor and includes a motor body 311 and an output shaft 312. The transmission unit 32 includes a first driving gear 321 and a second driving gear 322. The second driving gear 322 includes an eccentric shaft 3221. The first driving gear 321 is connected to the output shaft 312 of the driving motor 31. The second driving gear 322 is meshed with the first driving gear 321. The bottom end of the driving rod 33 has the connecting hole 331. The eccentric shaft 3221 of the second driving gear 322 is positioned in the connecting hole 331 of the driving rod 33. When the driving motor 31 is working, the first driving gear 321 connected to the output shaft 3221 is driven to rotate, thereby driving the second driving gear 322 to rotate, so that the eccentric shaft 3221 is displaced. The movement of the eccentric shaft 3221 drives the movement of the driving rod 33, thereby finally driving the plug body 20 to move in the cavity 10. When the first driving gear 321 and the second driving gear 322 complete a rotation cycle, the plug body 20 correspondingly generates a reciprocating movement cycle in the cavity 10 .

[0064] More specifically, when the drive motor 31 rotates, the output shaft 312 drives the first drive gear 321 and the second drive gear 322 to rotate, so as to drive the eccentric shaft 3221 to move toward the drive motor 31. At the same time, the drive rod 33 moves synchronously with the eccentric shaft 3221 toward the drive motor 31, so that the plug body 20 moves in the direction toward the drive motor 31 and away from the top wall 101 of the cavity 10, so that the volume of the first chamber 11 increases and gas is inhaled, thereby causing the air pressure in the space between the groove 13 and the opening 43 of the massage shell 40 to decrease, forming a negative pressure, thereby generating a suction massage on the human body parts.

[0065] When the output shaft 312 drives the first driving gear 321 and the second driving gear 322 to rotate and drives the eccentric shaft 3221 to move in a direction away from the driving motor 31, that is, the eccentric shaft 3221 reaches the bottom position and is driven by the second driving gear 322 to move upward, the driving rod 33 and the eccentric shaft 3221 move synchronously in a direction away from the driving motor 31, so that the plug body 20 moves in a direction away from the driving motor 31 and close to the top wall 101 of the cavity 10, so that the volume of the first chamber 11 is reduced and the gas is discharged, thereby causing the air pressure of the space between the groove 13 and the opening 43 of the massage housing 40 to increase and restore the initial air pressure. In this way, the above process is repeated, and the massage device can perform periodic suction massage on human body parts.

[0066] Reference Figure 6 and Figure 7 As shown in the arrangement direction of the structural components shown in the figure, when the plug body 20 is driven to move downward, air enters the first chamber 11 from the multiple through holes 14, so that the suction and discharge driving device 1 generates the suction force required by the massage device. When the plug body 20 is driven to move upward, air is discharged from the first chamber 11 from the multiple through holes 14, so that the suction and discharge driving device 1 returns to the initial state.

[0067] In this embodiment, the fixed housing 50 includes a first housing portion 51 and a second housing portion 52 , which are assembled to form a space for accommodating the suction and discharge drive device 1 , the controller 60 and the power module 60 .

[0068] More specifically, for example, the fixed shell 50 includes a positioning element 53, which forms a positioning groove 531. In this embodiment, the positioning element 53 includes a positioning plate arranged on at least one of the first shell part 51 and the second shell part 52, and the positioning groove 531 is formed in the middle of the positioning element 53. The cavity 10 of the suction and discharge drive device 1 is engaged in the positioning groove 531 to be positioned. It can be understood that in this embodiment, the first shell part 51 and the second shell part 52 can both include similar structures of the positioning element 511 and the positioning groove 531, so that when the first shell part 51 and the second shell part 52 are buckled, the cavity 10 of the suction and discharge drive device 1 is positioned in the fixed groove formed by the two positioning grooves 531, and an assembly chamber 532 is formed in the fixed shell 50 to accommodate the cavity 10 of the suction and discharge drive device 1.

[0069] The fixed shell 50 further has an end chamber 54, which is located on opposite sides of the positioning element 53 implemented as a positioning plate from the assembly chamber 532, and the end of the end chamber 54 has an end hole 541, and the end hole 541 corresponds to the opening 43 of the massage shell 40. The end chamber 54 is connected to the groove 13 on the top side of the cavity 10 of the suction and discharge drive device 1.

[0070] The end chamber 54 of the fixed shell 50 and the groove 13 of the air suction and discharge driving device 1 form an air pressure regulating chamber 501, which is connected to the through hole 14 of the air suction and discharge driving device 1 and the end hole 541 of the fixed shell 50 and the opening 43 of the massage shell 40. Therefore, when the air pressure in the first chamber 11 in the cavity 10 is adjusted, the air pressure change is generated in the air pressure regulating chamber 501 accordingly, so that the massage device generates suction, thereby acting on the human body part.

[0071] It is understandable that the groove 13 formed by the extending wall 103 of the cavity 10 plays a guiding role, so that the air in the end chamber 54 of the fixed shell 50 can enter the groove 13 and thus enter and exit the first chamber 11.

[0072] The fixed shell 50 further forms a motor chamber 55 having a through hole 551 , and the drive motor 31 can be fixed and accommodated in the motor chamber 55 , and the output shaft 312 of the drive motor 31 extends out of the motor chamber 55 through the through hole 551 to be coupled to the transmission unit 32 .

[0073] The motor chamber 55 and the assembly chamber 531 are connected and intersected, the transmission unit 32 is correspondingly arranged at the intersection of the motor chamber 55 and the assembly chamber 531, and the fixed shell has a bending point 502 at the position corresponding to the transmission unit 32. In this way, the cavity 10 and the drive motor 31 of the suction and discharge drive device 1 are reasonably arranged, and the overall size is made more compact.

[0074] In addition, the outer surface of the fixed shell 50 may have a plurality of fixing grooves 58, and the inner surface of the massage shell 40 may be correspondingly formed with a plurality of fixing protrusions, so that each of the fixing protrusions is retained in the corresponding fixing groove 58, so that the massage shell 40 can be firmly retained in the fixed shell 50.

[0075] The fixed housing 50 further forms a controller accommodating slot 56 and a power accommodating slot 57 between the first housing portion 51 and the second housing portion 52 to accommodate the controller 56 and the power module 70 respectively.

[0076] like Figures 9 to 14 , a massage device and an air suction and discharge drive device thereof according to a second embodiment of the present invention are shown, wherein the massage device comprises an air suction and discharge drive device 1, a flexible massage housing 40, a fixed housing 50, a controller 60 and a power module 70. The fixed housing 50 is used to fix the air suction and discharge drive device, the controller 60 and the power module 70, the massage housing 40 is sleeved outside the fixed housing 50, the controller 60 is used to control the operation of the air suction and discharge drive device 1, and the power module 70 supplies power to the controller 60 and the air suction and discharge drive device 1.

[0077] In this embodiment, an air suction and discharge drive device 1 for a massage device includes a cavity 10, a plug 20 movably disposed in the cavity 10, and a drive assembly 30 for driving the plug 20, wherein the plug 20 is disposed in the cavity 10 to form a space in the cavity 10 into a first chamber 11 and a second chamber 12 located on opposite sides of the plug 20, respectively; when the drive assembly 30 drives the plug 20 to reciprocate in the cavity 10, the size of the first chamber 11 and the second chamber 12 can be adjusted, so that the air pressure in the first chamber 11 can be adjusted, thereby providing the massage device with the required suction force.

[0078] In this embodiment, the chamber 10 has two through holes 14 on the top side, which are a first through hole 141 and a second through hole 142, wherein the chamber 10 further includes a plurality of one-way valves 15, which include an air intake one-way valve 151 disposed at the first through hole 141, and an air exhaust one-way valve 152 disposed at the second through hole 142, wherein the air intake one-way valve 151 allows air outside the chamber 10 to enter the first chamber 11 while the air in the first chamber 11 does not reach the outside of the chamber 10 through the air intake one-way valve 151. The air exhaust one-way valve 152 does not allow air outside the chamber 10 to enter the first chamber 11 via the air exhaust one-way valve 152, but allows air in the first chamber 11 to be discharged from the first chamber 11 through the air exhaust one-way valve 152 and reach the air pressure regulating chamber 501 outside the chamber 10.

[0079] Preferably, the intake check valve 151 is disposed at the bottom side of the first through hole 141, and the exhaust check valve 152 is disposed at the top side of the first through hole 142, so as to facilitate the guidance of airflow. Fig.14As shown in the figure, the air intake check valve 151 is attached to the bottom surface of the top wall 101 of the cavity 10, so that the first through hole 141 is located on the top side of the air intake check valve 151, so that when the plug body 20 is driven to move away from the top wall 101 to increase the volume of the first chamber 11, it is convenient for the air in the groove 13 to enter the first through hole 141, be buffered by the first through hole 141, and then flow through the air intake check valve 151 to enter the first chamber 11.

[0080] The exhaust check valve 152 is attached to the top side surface of the top wall 101 of the cavity 10 so that the second through hole 142 is located on the bottom side of the exhaust check valve 152, so that when the plug body 20 is driven to move toward the top wall 101 to exhaust the air in the first chamber 11, the air in the first chamber 11 is first guided into the second through hole 142, and then flows from the second through hole 142 through the exhaust check valve 152 to be discharged to the groove 13 of the cavity 10, thereby further entering the end chamber 54 of the fixed shell 50 to blow air toward the end hole 541 of the fixed shell 50 and the opening 43 of the massage shell 40.

[0081] It is understandable that each of the one-way valves 50 may be a structure that allows air to pass through and prevents air from flowing back, for example, a typical check valve structure including a valve core, a valve body, a return spring, and a steel ball. The air intake one-way valve 151 is arranged on the bottom side of the first through hole 141, so that during the inhalation process, the air in the air pressure regulating chamber 501 enters the first through hole 141 to accumulate air pressure through the first through hole 141, so that the higher air pressure in the first through hole 141 can enable the air intake one-way valve 151 to open the air intake path toward the first chamber 11. During the deflation process, the air pressure in the first chamber 11 cannot open the air intake one-way valve 151, so that air cannot enter the air pressure regulating chamber 501 through the first through hole 141.

[0082] The exhaust check valve 152 is disposed on the top side of the second through hole 142, so that during the deflation process, the air in the first chamber 11 first enters the second through hole 142 to accumulate air pressure through the second through hole 142, so that when a higher air pressure is reached in the second through hole 142, the exhaust valve 152 can open the deflation path toward the air pressure regulating chamber 501. During the inhalation process, the air pressure in the air pressure regulating chamber 501 cannot open the exhaust check valve 152, so that the air cannot enter the first chamber 11 through the second through hole 142.

[0083] Reference Figure 12 to Figure 14As shown in , when the plug body 20 is driven to move downward, air enters the first chamber 11 from the first through hole 141 via the air inlet check valve 151, so that the air suction and discharge driving device 1 generates the suction force required by the massage device. When the plug body 20 is driven to move upward, air is discharged from the first chamber 11 from the second through hole 14 via the air exhaust check valve 152, so that the air suction and discharge driving device 1 returns to the initial state.

[0084] In this embodiment, air enters the first chamber 11 from the air pressure regulating chamber 501 through the first through hole 141 and passes through the air inlet one-way valve 151, and the first chamber 11 enters the second through hole 142 and passes through the exhaust one-way valve 152 to enter the air pressure regulating chamber 501, thereby providing a smooth airflow path by the cavity 10 itself, ensuring that the massage device can periodically and continuously generate suction at the head end shell 42 of the massage shell 40 to massage human body parts.

[0085] Accordingly, the present invention provides a method for producing suction massage, which comprises a periodic air-inhalation step and an air-release step, so as to produce massage on a contacted human body part.

[0086] More specifically, in the suction step, the transmission unit 32 is driven by the drive motor 31 to drive the drive rod 33 to drive the plug body 20 to move in the cavity 10 to increase the volume of the first chamber 11, so that the air in the air pressure regulating chamber 501 enters the first chamber 11 through the through hole 14, so that suction is generated at the opening 43 of the massage shell 40 to act on the human body part.

[0087] In the deflation step, the transmission unit 32 is driven by the drive motor 31 to drive the drive rod 33 to drive the plug body 20 to move in the cavity 10 to reduce the volume of the first chamber 11, so that the air in the first chamber 11 enters the air pressure regulating chamber 501 through the through hole 14 to blow toward the opening 43 of the massage shell 40.

[0088] In this embodiment of the present invention, the eccentric shaft 3221 of the transmission unit 32 is driven to move reciprocatingly by the drive motor 31, thereby realizing the reciprocating lifting and lowering motion of the drive rod 33, thereby further driving the plug body 20 to move reciprocatingly in the cavity 10.

[0089] When the one-way valve 15 is provided in the through hole 14, in the air intake step, the transmission unit 32 is driven by the drive motor 31 to drive the drive rod 33 to drive the plug body 20 to move in the cavity 10 to increase the volume of the first chamber 11, so that the air in the air pressure regulating chamber 501 passes through the first through hole 141 and the air inlet one-way valve 151 into the first chamber 11, so that suction is generated at the opening 43 of the massage shell 40 to act on the human body part.

[0090] In the deflation step, the transmission unit 32 is driven by the drive motor 31 to drive the drive rod 33 to drive the plug body 20 to move in the cavity 10 to reduce the volume of the first chamber 11, so that the air in the first chamber 11 passes through the second through hole 142 and the exhaust one-way valve 152 into the air pressure regulating chamber 501 to blow toward the opening 43 of the massage shell 40.
